I don't quite understand why they would come up with such confusing definitions. In the "real" world of copyrights, I post a lot of my stuff as CC, but with the restriction of "Attribution-Non-Commercial-No Derivatives": https://creativecommons.org/licenses/by-nc-nd/2.0/
So why they tried to re-invent the wheel is beyond me, since all these different licenses are already part of the legal framework of Copyright and Creative Commons.
